“Whether a coincidence or not, there was not a single death in the Washoe tribe from influenza or its complications, although Indians living in other parts of the State where the root did not grow died in numbers. It was such a remarkable coincidence that the root was investigated by a practicing physician who saw apparently hopeless cases recover without any other medication or care of any kind. A preparation was prepared and employed in a great many cases among the whites, from the mildest to the most virulent types of influenza, and it proved, among other things, that it is the nearest approach we have today to a specific in epidemic influenza and the accompanying pneumonia.”
